AS 1246 Push and Pull Solenoid with Long stroke...
Part 1: Long Stroke Solenoid Working Principle
The long-stroke solenoid is mainly composed of a coil, a moving iron core, a static iron core, a power controller, etc. Its working principle is as follows
1.1 Generate suction based on electromagnetic induction: When the coil is energized, the current passes through the coil wound on the iron core. According to Ampere's law and Faraday's law of electromagnetic induction, a strong magnetic field will be generated inside and around the coil.
1.2 The moving iron core and the static iron core are attracted: Under the action of the magnetic field, the iron core is magnetized, and the moving iron core and the static iron core become two magnets with opposite polarities, generating electromagnetic suction. When the electromagnetic suction force is greater than the reaction force or other resistance of the spring, the moving iron core begins to move toward the static iron core.
1.3 To achieve linear reciprocating motion: The long-stroke solenoid uses the leakage flux principle of the spiral tube to enable the moving iron core and the static iron core to be attracted over a long distance, driving the traction rod or push rod and other components to achieve linear reciprocating motion, thereby pushing or pulling the external load.
1.4 Control method and energy-saving principle: The power supply plus electric control conversion method is adopted, and the high-power start-up is used to enable the solenoid to quickly generate sufficient suction force. After the moving iron core is attracted, it is switched to low power to maintain, which not only ensures the normal operation of the solenoid, but also reduces energy consumption and improves work efficiency.
Part 2 : The main characteristics of the long-stroke solenoid are as follows:
2.1: Long stroke: This is a significant feature. Compared with ordinary DC solenoids, it can provide a longer working stroke and can meet the operation scenarios with higher distance requirements. For example, in some automated production equipment, it is very suitable when objects need to be pushed or pulled for a long distance.
2.2: Strong force: It has sufficient thrust and pulling force, and can drive heavier objects to move linearly, so it can be widely used in the drive system of mechanical devices.
2.3: Fast response speed: It can start in a short time, make the iron core move, quickly convert electrical energy into mechanical energy, and effectively improve the working efficiency of the equipment.
2.4: Adjustability: The thrust, pull and travel speed can be adjusted by changing the current, number of coil turns and other parameters to adapt to different working requirements.
2.5: Simple and compact structure: The overall structural design is relatively reasonable, occupies a small space, and is easy to install inside various equipment and instruments, which is conducive to the miniaturization design of the equipment.
Part 3 : The differences between long-stroke solenoids and comment solenoids :
3.1: Stroke
Long-stroke push-pull solenoids have a longer working stroke and can push or pull objects over a long distance. They are usually used in occasions with high distance requirements.
3.2 Ordinary solenoids have a shorter stroke and are mainly used to produce adsorption within a smaller distance range.
3.3 Functional use
Long-stroke push-pull solenoids focus on realizing the linear push-pull action of objects, such as being used to push materials in automation equipment.
Ordinary solenoids are mainly used to adsorb ferromagnetic materials, such as common solenoidic cranes that use solenoids to absorb steel, or for adsorption and locking of door locks.
3.4: Strength characteristics
The thrust and pull of long-stroke push-pull solenoids are relatively more concerned. They are designed to effectively drive objects in a longer stroke.
Ordinary solenoids mainly consider the adsorption force, and the magnitude of the adsorption force depends on factors such as the magnetic field strength.
Part 4 : The working efficiency of long-stroke solenoids is affected by the following factors:
4.1 : Power supply factors
Voltage stability: Stable and appropriate voltage can ensure the normal operation of the solenoid. Excessive voltage fluctuations can easily make the working state unstable and affect efficiency.
4.2 Current size: The current size is directly related to the strength of the magnetic field generated by the solenoid, which in turn affects its thrust, pull and movement speed. The appropriate current helps to improve efficiency.
4.3 : Coil related
Coil turns: Different turns will change the magnetic field strength. A reasonable number of turns can optimize the performance of the solenoid and make it more efficient in long-stroke work. Coil material: High-quality conductive materials can reduce resistance, reduce power loss, and help improve work efficiency.
4.4: Core situation
Core material: Selecting a core material with good magnetic conductivity can enhance the magnetic field and improve the working effect of the solenoid.
Core shape and size: The appropriate shape and size help to evenly distribute the magnetic field and improve efficiency.
4.5: Working environment
- Temperature: Too high or too low temperature may affect the coil resistance, core magnetic conductivity, etc., and thus change the efficiency.
- Humidity: High humidity may cause problems such as short circuits, affect the normal operation of the solenoid, and reduce efficiency.
4.6 : Load conditions
- Load weight: Too heavy a load will slow down the solenoid's movement, increase energy consumption, and reduce work efficiency; only a suitable load can ensure efficient operation.
- Load movement resistance: If the movement resistance is large, the solenoid needs to consume more energy to overcome it, which will also affect efficiency.

What is a small push-pull solenoid
Push-Pull Solenoid is a subset of electromechanical devices and a fundamental component in various applications across all of the industries. From smart door locks and printers to vending machines and car automation systems, these push-pull solenoids contribute significantly to the seamless operation of these devices.
How the small Push-Pull Solenoid work ?
A push-pull solenoid operates based on the concept of electromagnetic attraction and repulsion. When an electrical current goes through the coil of the solenoid, it generates a magnetic field. This magnetic field subsequently induces a mechanical force on a movable plunger, causing it to move in linear direction of the magnetic field, thereby ‘pushing’ or ‘pulling’ as required.
Push movement action: The solenoid ‘pushes’ when the plunger is extended out of the solenoid body under the influence of the magnetic field.
Pull movement action: Conversely, the solenoid ‘pulls’ when the plunger is drawn into the solenoid body due to the magnetic field.
Construction and Working Principle
Push-pull solenoids consist of three primary components – a coil, a plunger, and a return spring. The coil, typically made of solenoid copper wire, is wound around a plastic bobbin, forming the body of the solenoid. The plunger, usually composed of ferromagnetic material, is positioned within the coil, ready to move under the influence of the magnetic field. The return spring, on the other hand, is responsible for returning the plunger to its original position once the electric current is turned off.
When an electric current flows through the solenoid coil, it creates a magnetic field. This magnetic field induces a force on the plunger, causing it to move. If the magnetic field is aligned such that it pulls the plunger into the coil, it is termed as the ‘pull’ action. Conversely, if the magnetic field pushes the plunger out of the coil, it’s the ‘push’ action. The return spring, located at the opposite end of the plunger, pushes the plunger back to its original position when the current is turned off, thus resetting the solenoid for the next operation.

What is DC Linear Solenoid ?
DC linear solenoid ( it is also call linear actuator ) features robust linear movement and are well suited for "heavy duty" applications. This kind of DC linear solenoid design allows high holding force at a comparably low current. Therefore push pull solenoids are ideal actuators for applications for which power consumption and heat dissipation are critical. It is named "Push/Pull" because both shaft ends are available, so the linear solenoid can be used as pushing solenoid or pulling solenoid, depending which shaft end is used for mechanical connection - but because of reluctance working principle the active moving direction when powering the coil is only unidirectional. Applications can be found in medical, laboratory and analytical equipment.

How Does a Push Pull Solenoid Actuator Work ?
AS 0635 Push Pull Solenoid actuator powered unit is Push-Pull open frame type, with linear motion and plunger spring return design, open solenoid coil form, DC electron magnet. It has been used widely in home appliances, vending machines, a game machine.....
Efficient and durable push-pull solenoids generate a significant amount of force for their comparatively small size, this makes the push pull particularly suited to high-force short-stroke applications.
The compact size of the solenoid optimises the magnetic flux path, alongside a precision coil winding technique which packs the maximum amount of copper wire into the available space, allowing maximum force to be generated.
Push-pull solenoids have 2 shafts relative to the mounting studs, the shaft on the same side as the studs pushes and the shaft on the armature side pulls, so you have both options on the same solenoid. As opposed to other solenoids like tubulars which are independent of each other.
It is steady, durable and energy-saving, and had a long lifespan with more than 300,000 cycle time. In the anti-theft and shockproof design, the lock is better than other kinds of locks. After connecting the wires and when the current is available, the electric lock can control the door’s opening and closing.
Note: Take care of polarity while making the connection without a connector (i.e. Red wire should be connected to the positive and Black wire to the negative.)

AS 0420 A Push and Pull Solenoid For Shared Cha...
Part 1 : What is a sharing charging station solenoid ?
sharing charging station solenoid is an electromagnetic device used in shared power banks.
Structurally, it is composed of a single electromagnet, which can be combined into a group of 6 or 12 electromagnets. A single solenoid is mainly composed of a copper coil, an iron core and an armature. The copper coil is wound with an insulated wire and is the key part of generating a magnetic field when powered on; the iron core is generally made of soft magnetic materials (such as silicon steel sheets) to enhance the strength of the magnetic field; the armature will move under the action of the magnetic field.
Part 2 : The working principle of the charging station solenoid ?
When current passes through the copper coil, a magnetic field is generated that magnetizes the iron core, thereby generating a strong electromagnetic suction force. In shared power bank devices, this suction force is mainly used to control the locking and ejection of the power bank. For example, after the power bank is returned, the solenoid is energized, and the suction force generated will lock the power bank firmly in the charging cabinet; and when the user rents the power bank, the system controls the solenoid to cut off the power or change the direction of the current, so that the suction force disappears or decreases, so that the power bank can be ejected smoothly into the machine.
Part 3 : The advantage and disadvantage of charging station solenoid?
3.1: Easy control: The presence, strength and direction of its magnetism can be accurately controlled by turning on and off the current. For example, the charging cabinet controls the current on and off to unlock or lock the power bank, which is simple and accurate to operate.
3.2: Fast response: After power is turned on, it can quickly generate a magnetic field, with a large control torque, and can quickly realize the ejection and locking of the power bank, improving the user experience.
3.3 : Simple structure: It is mainly composed of a coil, an iron core and an armature, with a relatively simple structure, easy to install and maintain, reducing production costs and maintenance difficulties.
3.4: quiet operation: The sound generated during operation is weak and will not cause noise interference to the surrounding. It is suitable for application in various places, such as shopping malls, offices, trading fair....etc.
3.5: Strong carrying capacity: It has strong magnetism and can withstand a certain load, ensuring the stability of the power bank in the locked state and preventing it from accidentally falling off.
The main disadvantages of sharing Charging station Solenoid are:
3.6: Dependence on power supply: It requires an external power supply and cannot work without power supply. Once there is a problem with the power supply of the charging cabinet, the solenoid will not be able to control the power bank normally.
3.7: Low efficiency: Controlling the size of the magnetic force usually consumes a lot of electricity, and its own efficiency is relatively low. Long-term operation will increase certain operating costs.
3.8: High heat generation: When powered on, it will generate a lot of heat. Long-term operation may cause the temperature to be little high, affecting the performance and life. Therefore, heat dissipation measures need to be taken, which increases the complexity and cost of the equipment.
3.9: Risk of wear and tear: After long-term and frequent operation, the armature and other parts of the solenoid will be worn and corroded, and need to be regularly inspected and replaced, otherwise it may fail and affect the normal operation of the power bank.
